When coding in Java in Eclipse, is there a shortcut similar to typing "syso" and pressing CTRL+Space for System.out.println(), but for printf instead of println?
you can create your own using eclipse template functionality.
To create your own template take a look here Window->Preferences->Java->Editor->Templates.
For example the sysout functionality has this template:
System.out.println(${word_selection}${});${cursor}
you can create similar for System.out.print()
You can make your own for printf:
In preferences choose Java->editor->templates.
I don't see one in the default completion templates, but you can create your own template
I created my own System.out.printf() shortcut on Eclipse.
Simply, go to Windows > Preferences > Java > Editor > Templates
Click on New, then fill the form with the following information:
Name: the shortcut you would like to use in the editor (e.g. printf)
Description: print formatted text (or any other description)
Pattern: System.out.printf(${word_selection}${});${cursor}
That's it! Now you can just type "printf" in your editor, followed by [Ctrl + space], then [Enter], and the editor will place a System.out.printf() for you.
If you name the new Templates as pzf (you can also try different combinations and see if that doesn't match any other Template names) it will print the statement right away, without having to press enter. Also, I added inverted commas and commas.
System.out.printf("${word_selection}${}",);${cursor}

I am aware of the Eclipse snippet "sysout" which is neatly replaced with System.out.println(); when tab-completed.
This is very useful but sometimes, I need to wrap some existing code in a System.out.println();
In Eclipse internals, the template is defined as being able to wrap a "selected word". But how can I use the snippet with selected text since typing "sysout" obviously removes the selected text.
Any idea?
The sysout template acts upon entire Java statements.
Highlight a statement in the editor.
Hit CTRL-SPACE (or whatever you have set up for content assist.)
Type sysout then hit enter. Note that when you're typing sysout it will temporarily overwrite your statement (but it will come back wrapped by System.out.println when you hit enter.)
Eclipse has "Surround Width" Option which can do this for you.
SHIFT + ALT + Z should get you that to see how that templates meta-data layout.
I don't think you can do it in one go, but what about cutting the selected text and then: tab+space, ctrl+v
it's just one key combination more.
if you use content assist (ctrl-space on Windows), at the end of the list will be the sysout option. you might want to augment the template with quotes around the word selection so you dont need to type them in.
Preference>General>Keys.
then search "content assist" or "content" in "type filter text".
don't press Enter.
choice "content assist".
type Binding and set your own shortcuts.
such as "control+space".
The main part is into:
Java->Editor->Templates
This can accessed by:
Preferences window: into Java->Editor->Templates.
Surrounding a text and press:
Windows: SHIFT + ALT + Z (as sadhasivam said)
Mac: CMD + OPT + Z
to display the Preferences Window
In Eclipse, when i select part of a text and press any key, the whole selection is replaced.
I would like to know how to make it, instead of replacing the text, add the key pressed to both ends of the selection, as it happens on visual studio code.
Example:
System.out.println(HelloWorld);
Select Hello World
System.out.println(HelloWorld);
Then press the " button. The code will turn to
System.out.println(");
Can i config the IDE so it will instead change it to
System.out.println("HelloWorld");
There is a already answered question like this one, but considering that one as 7 years and a lot of version old, and also considering that the answer on that one is kind of a work around, i would like to know if there's any new plugin or configuration that make it work better
From what I gather, you are wanting to do something like this?
Go to Java > Editor > Templates and add a new template, e. g. called quote, as follows:
"${word_selection}"${cursor}
Then, in the editor, write a text you want to quote, select it, press Ctrl+Space, type quote and hit Return. The highlighted text should be quoted now.
If you don't get template proposals when pressing Ctrl+Space, make sure you have them checked in Java > Editor > Content Assist > Advanced.
Just tried it and it works for me!
You can use this method for other things, like (${word_selection})${cursor} for parenthesis or '${word_selection}'${cursor} for single quote.
When I reformat code with Eclipse, it turns method headers like this:
public void myMethod(String param) {
into method headers like this:
public void myMethod(
String param) {
When I was brought on here I'd never used Eclipse before, and I imported project settings provided by someone else. I have seen that on small new projects I've worked on Eclipse does not do this, so it must be in the settings I've imported. But I've gone through every panel I can find, as well as every hidden file I can find in the workspace, and I can't figure out what is causing this.
How do I turn it off? I don't want a newline before parameters in my method signatures, and I can't imagine why anyone would!
Have a look at Window>Preferences>Java>Code Style>Formatter.
There you can configure almost everything. Your case is found at
Line Wrapping>Method Declarations>Parameters.
In my version of Eclipse, I found the option under Window->Preferences->Java->Code Style->Formatter, then clicked the Edit.. button.
In the new window, go to the Line Wrapping tab and find Method Declarations. You want to change the Line wrapping policy. The Force split check box seems to do the same.
Go into preferences: Java -> Code Style -> Formatter
Restore Defaults or edit what's there.
Additionally, Code Style -> Code Templates will allow you to define generate code formatting.
Note that this is for Eclipse Workspace as a whole, the same Preferences can be accessed under the project preferences if you want to get more fine grained at a per project level.
In eclipse you can define your code formatting use Code Style ,
for MAC System :--> Eclipse --> Preference -- > java--> code Style
for Window System :--> Window->Preferences->Java->Code Style->Formatter
The best way to change your format is to go to Window-> Preferences-> Java-> Code Style-> Formatter. Inside the formatter window, eclipse has a couple of built in styles, but the best way is create a new profile of your own by pressing on New. You can change the format as you please on the edit tab
You can change parentheses and curly braces positioning along with other stuff.
Lets say I have this method signature:
public String get(){};
Is there any shortcut in IntelliJ to highlight String and surround it with List<> So I can get the following:
public List<String> get(){};
You can make your own Surround Live Template:
Go to Settings/Preferences > IDE Settings > Live Templates > surround.
Add a new template.
Fill in the form
The abbreviation is used to select from the Surround With context menu.
The Description will appear in the Surround With context menu.
The $SELECTION$ variable is predefined as, you guessed it, the selected text.
You can add your own variables, such as $COLL$ to make the template more generic.
Set the Applicable in... to all of Java (or you can be more exact if you want).
To use it:
Select text.
Press Ctrl+Alt+T on Windows or ⌥⌘T on Mac
The Surround With context menu will appear with your new template.
Press C (since that's the first letter of the template's abbreviation) to quickly select the template.
IntelliJ blog post about this feature: "Surround with..."
Thanks for the answer and this is how we can create a variable :
Say I type "sout", the intellisense should expand it to "System.out.println()". Is there a way to adding such templates?
The feature is called "code templates" in Eclipse. You can add templates with:
Window->Preferences->Java->Editor->Templates.
Two good articles:
Don't write the code, generate it
Custom Templates

Useful Eclipse Java Code Templates
System.out.println() is already mapped to sysout, so you may save time by learning a few of the existing templates first.
Type "Sysout" and then Ctrl+Space. It expands to
System.out.println();
Type syso and ctrl + space for System.out.println()
type "syso" and then press ctrl + space
OR
type "sysout" and then press ctrl + space
This is one more option: go to Windows > Preference > Java > Editor > Content Assit. Look in "Auto Activation" zone, sure that "Enable auto activation" is checked and add more charactor (like "abcd....yz, default is ".") to auto show content assist menu as your typing.
I've been Eclipse-free for over a year now, but I believe Eclipse calls these "Templates". Look in your settings for them. You invoke a template by typing its abbreviation and pressing the normal code completion hotkey (ctrl+space by default) or using the Tab key. The standard eclipse shortcut for System.out.println() is "sysout", so "sysout" would do what you want.
Here's another stackoverflow question that has some more details about it:
How to use the "sysout" snippet in Eclipse with selected text?
Step 1 -> Top apple icon -> System preference -> keyboard -> Shortcut>spotlight -> uncheck.
Step 2 ->Eclipse -> General -> keys -> search -> content Assist ->
Binding (cmd button + space) -> Apply&close.
